The invention belongs to the technical field of structural vibration reduction and isolation, and particularly relates to a damping-attached three-dimensional variable-rigidity limiting vibration isolation device which comprises a connecting part, a first vibration reduction mechanism, two second vibration reduction mechanisms and a third vibration reduction mechanism, and the second vibration reduction mechanisms and the third vibration reduction mechanism are connected into an integral structure through the connecting part; establishing a space rectangular coordinate system by taking the length direction of the connecting part as an X axis, the width direction as a Y axis and the height direction as a Z axis; the first damping mechanism is used for damping vibration in the X-axis direction and buffering force in the X-axis direction; the two second damping mechanisms are used for damping vibration in the Y-axis direction and buffering force in the Y-axis direction; the third damping mechanism is arranged at the top of the first damping mechanism, and the third damping mechanism conducts damping on vibration in the Z-axis direction and buffers force in the Z-axis direction. The three-dimensional shock isolation device can be applied to three-dimensional shock isolation, can provide positive rigidity to limit the displacement of the shock isolation layer during small earthquakes, and can provide negative rigidity to achieve the shock isolation effect during medium earthquakes and large earthquakes.
本发明属于结构减隔振技术领域，具体涉及一种附带阻尼的三维变刚度限位隔震装置，装置包括连接部、第一减震机构、两第二减震机构、第三减震机构，连接部将第二减震机构与第三减震机构连接为一个整体结构；以连接部的长度方向为X轴、宽度方向为Y轴，高度方向为Z轴，建立空间直角坐标系；第一减震机构对X轴方向的振动进行减震，缓冲X轴方向的力；两第二减震机构对Y轴方向的振动进行减震，缓冲Y轴方向的力；第三减震机构设置在第一减震机构顶部，第三减震机构对Z轴方向的振动进行减震，缓冲Z轴方向的力。本发明可以运用于三维隔震中，能够实现小震时提供正刚度限制隔震层位移，中震、大震时提供负刚度实现隔震效果。
